Ultra Magnus adopted the dear little (sent from hell) kitties found on his doorstep though since then he has regretted it. Not only did he have to buy collars, buy kitty food and kitty toys but he has to put up with their antics.

Roddy loves to annoy him wherever he goes and whatever he does.

Drift just follows Roddy's lead and uses his claws on all of Ultra Magnus's possessions...including the morning paper.
